Chicken Fajita Casserole Recipe
Here’s everything required to make this creamy, cheesy Easy Chicken Fajita Casserole:
- 10 boneless, skinless chicken thighs (about 2 lbs) – tender, juicy, and full of flavor
- 1 red bell pepper – seeded and thinly sliced into strips
- 1 large onion – peeled and sliced into strips for sweetness and depth
- 8 oz cream cheese – softened for a creamy base
- 8 oz shredded cheddar cheese – divided, half for mixing and half for topping
- 1 ½ tbsp fajita seasoning – smoky, spicy, and zesty
- Salt & black pepper – optional, adjust to taste
Step-by-Step Instructions
1. Bake the Chicken
Preheat your oven to 350°F (175°C). Place chicken thighs in a casserole dish, cover with foil, and bake for 30–35 minutes or until the internal temperature reaches 160°F. Let it rest for a few minutes, then shred or chop into bite-sized pieces. Discard extra liquid from the dish.
2. Caramelize the Veggies
While the chicken bakes, heat a skillet with cooking spray over medium-low heat. Add sliced bell pepper and onion, cooking slowly until soft and golden. Stir every 5–10 minutes for even caramelization, then set aside.
3. Mix the Filling
In a large bowl, combine cream cheese, half of the cheddar cheese, and fajita seasoning. Fold in shredded chicken, peppers, and onions.
4. Assemble & Bake
Transfer the mixture back to the casserole dish. Top with the remaining cheddar cheese. Bake for 25–30 minutes, until bubbly, hot, and golden on top.
Notes & Tips
- Make Ahead: Prepare up to Step 3, refrigerate for 2 days, then bake when ready (add 10–15 minutes extra baking time).
- Adjust Seasonings: Depending on your fajita mix, taste and adjust salt or spice before baking.
- Cheese Swap: Try Monterey Jack or Pepper Jack for extra melty goodness.

This Chicken Fajita Casserole is versatile and pairs perfectly with:
- A side of Spanish rice or cauliflower rice (low-carb option)
